Which of the following cells primarily perform phagocytosis?

Lymph consists of 96% water and 4% solids.

Milk contains 50-60% solids.

Cerebrospinal fluid is formed in the cavities of the heart.

Amniotic fluid volume increases with gestational age.

Cerebrospinal fluid acts as a hydraulic shock absorber.

Lymph transports only glucose to tissues.

The primary protein found in milk is lactalbumin.

Sweat is considered one of the specialized fluids of the body.

Electrolytes in lymph include calcium and magnesium.

The volume of cerebrospinal fluid is not regulated in the body.

The total amount of fluid in the human body is approximately 70% of body weight.

Intracellular fluid (ICF) makes up 45% of total body water.

The most abundant cation in extracellular fluid (ECF) is potassium (K+).

Plasma accounts for approximately 80% of the extracellular fluid.

The most abundant anion in intracellular fluid (ICF) is proteins and phosphates.

Water is solely responsible for transporting nutrients and oxygen in the body.

The Na+/K+ pumps are responsible for maintaining high levels of sodium outside the cell.

Interstitial fluid is located entirely within the bloodstream.

Sweat is primarily composed of water and is important for regulating body temperature.

Osmosis involves the movement of solutes across a semipermeable membrane.

Body fluid composition includes gases such as oxygen and carbon dioxide.

Hypotonic solutions have a higher solute concentration compared to the cell's interior.

In a hypertonic solution, water will move into the cell from the surrounding solution.

There are barriers that separate intracellular fluid, interstitial fluid, and plasma.

Facilitated diffusion requires energy to move molecules across the cell membrane.

Chemical reactions in the body depend on the presence of water.

A hypotonic solution causes water to leave the cell.

Simple diffusion continues until the concentration gradient is eliminated.

Synovial fluid, made mostly of water, provides lubrication for the joints.

Glucose is soluble in lipids and does not require carrier proteins to cross the cell membrane.

Filtration allows only small solutes to pass through membrane pores, as seen in the Bowman's capsule in the kidneys.

Endocytosis is a process that enables cells to expel substances from inside the cell.

Receptor-mediated endocytosis involves specific receptors binding to large molecules outside the cell.

Phagocytosis is the process where all cell types ingest small molecules and fluids.

The sodium-potassium pump is an example of passive transport in the human body.

Exocytosis is a process that requires energy to move substances from the cytoplasm to the outside of the cell.

Pinocytosis involves the engulfment of relatively large molecules and particles by the cell.

The movement of particles through the plasma membrane in vesicles occurs only in plant cells.

Hydrostatic pressure is involved in the process of filtration across cell membranes.
